Title: Manufacture of hub for disk cartridge
Inventor: AKAOKA KENKICHI
IPC: G11B23/00
Filed: 1986-04-23
Abstract: PURPOSE:To accurately decide the position of a disk metallic member in a metallic mold and to prevent the position deviation at open/close state of the metallic mold by providing a notch to the peripheral of the disk shaped metallic member constituting the base of a hub. CONSTITUTION:At least one notch 62 is provided to the periphery of the disk shaped metallic member 36 constituting the base of the hub inserted to a magnetic disk drive window of a hard case and having a projection 48 at the position where a resin mold wall part is formed protrusively for positioning a magnetic disk domain. Since the location of the discord metallic member 36 in the metallic mold is decided based on the notch 62, the accurate positioning is executed quickly. In fixing the location of the notch 62 at the metal mold opening/closing, since no position deviation is caused, the accuracy of shape of the hub is obtained and even if a projection 48 exists at the position where the resin mold wall part of the disk shaped metallic member 36 is formed protrusively, the projection 48 does not damage the metallic mold.

Title: Semiconductor element
Inventor: KUDO SUMIHISA
IPC: H01L29/778
Filed: 1989-04-13
Abstract: PURPOSE:To increase carrier concentration of a two-dimensional electron gas and improve mobility and saturation rate of the carrier by providing a layer where a mixed crystal ratio y of In changes continuously from 0 to y between a GaAs layer and an InyGa1-yAs layer. CONSTITUTION:A layer 4 called a graded layer where the mixed crystal ratio of In changes from 0 to y continuously from a GaAs layer 3 toward the InyGa1-yAs layer 5 is provided between the undoped GaAs layer 3 and the undoped InyGa1-yAs layer 5 to relax distortion due to difference in lattice constant between GaAs and InGaAs. As a result, since the undoped InyGa1-yAs layer 5 is relaxed due to presence of the graded layer 4, the thickness may be increased by that amount and the mixed crystal ratio y can be increased. Thus, the carrier concentration becomes larger and the mobility and saturation rate of carrier can be improved.

Title: Malfunction warning device of electric shutter utilizing electromagnetic device combining permanent magnet
Inventor: ISHIGURO YASUO
IPC: G03B9/62
Filed: 1978-08-05
Abstract: PURPOSE: To enable photographing to be adequately accomplished by discriminating the attraction and detaching of the iron piece lever of the electromagnetic deveice from the presence or not of its electromotive force generation and warning the detaching state of the iron piece lever.  
     CONSTITUTION: When a shutter button is pushed, a switch S 1  is changed over to the terminal b through moving up of a mirror and the coil L 1  for opening release is supplied with current. If at this time an iron core lever 3 is held attracted to an iron core 1, electromotive force is generated when i detaches but when the lever3 is held detached, no electromotive force is generatd. Hence, this is discriminated with a comparator COM 1  and the outpt of FF 2  is made to the signal level corresponding to either state. The similar operations also take place with the coil for closing and when at least one of the iron core levers is held detached, a transistor T 3  conducts through a NAND gate NAND 2  and buffer B, causing an LED to emit light and give warning. In this way, photographing may be accomplished adequately.

Title: Performance information evaluating device, its method and recording medium
Inventor: TOUGI ATSUSHI
IPC: G10H1/00
Filed: 1998-04-08
Abstract: PROBLEM TO BE SOLVED: To accurately measure the performance timing deviation of a player performing with his/her free tempo without strictly following the tempo of an etude and to evaluate a performance technique based thereon. SOLUTION: A performance data supplying means supplies performance data about an etude. A performed data supplying means supplies performed data when a player performs the etude. An extracting means extracts to which pronounced timing data of the performed data the pronouncing timing data of a certain sound pitch corresponding to the performance data corresponds. An evaluation value calculating means makes the ratio of the extracted pronounced timing data to the pronouncing timing data evaluation value. Since the evaluation value is a relative value that shows how much performed data is deviated from the performance data and is performed, when the evaluation value is different from another value, an evaluating means decides that the player hesitates or makes a mistakes at that place and evaluates performance itself that is performed by the player.

Title: Heterojunction-type phototransistor
IPC: H01L31/10
Filed: 1992-03-24
Abstract: PURPOSE:To obtain a heterojunction-type phototransistor wherein a large electric current and a large optical gain can be obtained by a method wherein a semiconductor layer for emitter use is formed of In1-w(Ga1-xAlx)wAs. CONSTITUTION:Compositions (w) and (x) in a semiconductor layer 25 for emitter use are set to be the energy range of Ei which reduces the sum of a semiconductor layer 4 for base use and a semiconductor layer 3 for collector use to a minimum during the traveling operation of electrons. As a result, the title phototransistor can be operated at extremely high speed. In addition, InP 22 which is provided with a transmitting property with reference to light having a wavelength of about 0.92mum or higher is used as a semiconductor layer for subcollector use. As a result, it functions as a window with reference to light having a long wavelength, and light can be made incident from the rear of a semiinsulating semiconductor substrate 1. Consequently, when a substrate which does not absorb the wavelength of light as an object is used as the substrate 1, the interference between an emitter mesa side face and the semiconductor layer 4 for base use is electrically stable. Since a leakage current through the part is reduced, the large electric current and the large optical gain of the title phototransistor can be obtained.

In a section between B and C where the same value for setting of the telescope is used for the reference line 1, a perpendicular 8 is drawn from the beginning point B to the tangent line 3, and a perpendicular 9 is drawn from the ending point C to the tangential line 3. A line connecting the beginning point B and the ending point C is made to be a collimation axis 4 for the telescope. A point where the perpendicular 8 intersects the tangent line 3 is made to be the point B', a point where the perpendicular 9 intersects the tangent line 3 is made to be the point C' and a point where the collimation axis 4 intersects the setting line 5 is made to be the point D. Then, by specifying B' S=alpha, C' S=beta and D S=F, the value F for setting of the telescope is calculated with an equation F=alphabetadivided by 2R.
